Description

Drying oven

Technical field

The present invention relates to technical field of processing equipment, in particular to a kind of drying oven.

Background technology

Air-conditioner (off-premises station and off-premises station) to fin punching, copper pipe bend pipe, expander processing in all use volatility to moisten Lubricating oil, then in follow-up processing again the lubricating oil on fin and copper pipe is carried out dry defat, with ensure welding performance and Coolant uses environment.

In prior art, drying oven is, under certain in-furnace temperature environment, two devices (off-premises station and off-premises station) are carried out entirety Heating, drying, and for final resid amount, the drying temperature in drying oven in improving two device drying efficiencies and reducing by two device copper pipes Higher, long-term operation energy consumption continuously is bigger.

Summary of the invention

The embodiment of the present invention provides a kind of drying oven, to solve the problem that in prior art, drying oven energy consumption is bigger.

For achieving the above object, the invention provides a kind of drying oven, for air-conditioner parts carry out drying defat, empty Adjusting device parts to include fin and copper pipe, drying oven has the drying chamber accommodating air-conditioner parts, and drying oven is additionally provided with air blowing dress Putting, blowning installation is movably disposed in drying chamber, and blowning installation dries indoor temperature for blowing out ratio towards the mouth of pipe of copper pipe High compressed gas.

Further, blowning installation can move along the short transverse of copper pipe putting position.

Further, blowning installation has multiple spaced air nozzle, and air nozzle is correspondingly arranged with the mouth of pipe of copper pipe.

Further, each air nozzle can individually be opened or close.

Further, the difference between compressed gas temperature and the drying chamber temperature of blowning installation blowout is Celsius more than 50 Degree.

Further, the temperature in drying chamber is between 130 degrees Celsius and 160 degrees Celsius.

Further, also including exhaustor, exhaustor connects with drying chamber.

Further, also including combustor, combustor is for promoting the temperature in drying chamber.

The drying oven of the technical program by the heat energy by drying fin and copper pipe separately, keeps in the drying chamber of drying oven Relatively low in-furnace temperature, is dried fin by temperature relatively low in drying chamber, and synchronizes by blowning installation with relatively The compressed air of high-temperature blows to inside copper pipe, and to realize the quick removing of the internal Residual oil of copper pipe, so drying indoor temperature is low, Without high energy consumption, because realizing the heat energy distribution according to need that each takes what he needs, and then heat energy efficiency can be maximally utilised, thus real Now reduce the energy consumption of drying oven.

Accompanying drawing explanation

Fig. 1 is the structural representation of the drying oven of the embodiment of the present invention.

Detailed description of the invention

With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but not as the limit to the present invention Fixed.

By theory analysis and experimental data, the drying oven of prior art is illustrated: residual after air-conditioner processing Volatilized lubricant is mainly in remaining in the inwall of fin and copper pipe, and the lubricating oil on fin is readily volatilized, and in drying oven Circulating fan drives air current flow, the volatilization that therefore fin is dried only to need a small amount of heat energy.And copper pipe is the semiclosed knot of long U-shaped Structure, the ethereal oil of residual therein is difficult to remove.

According to above-mentioned situation, according to embodiments of the invention, it is provided that a kind of drying oven, for air-conditioner parts are entered Row dries defat, and air-conditioner parts include fin and copper pipe, as it is shown in figure 1, drying oven has the drying accommodating air-conditioner parts Room 10, drying oven is additionally provided with blowning installation 20, and blowning installation 20 is movably disposed in drying chamber 10, and blowning installation 20 is used The compressed gas that temperature is high in blowing out than drying chamber 10 towards the mouth of pipe of copper pipe.

Blowning installation 20 can move along the short transverse of copper pipe putting position.Blowning installation 20 can pass through lever arm Or adjustable shelf moves, blowning installation 20 can move up and down according to the height putting into drying chamber air supply rate, with Realize closely being directed at the mouth of pipe of copper pipe.

In order to increase drying efficiency, and the mouth of pipe of corresponding copper pipe, in the drying oven of the present embodiment, blowning installation 20 has Multiple spaced air nozzles 21, air nozzle 21 is correspondingly arranged with the mouth of pipe of copper pipe.Blowning installation 20 is facilitated to control, with The air-conditioner parts of different model are dried, so each air nozzle 21 can individually be opened or close.

Difference between compressed gas temperature and drying chamber 10 temperature of blowning installation 20 blowout is more than 50 degrees Celsius.Dry Temperature in room 10 is between 130 degrees Celsius and 160 degrees Celsius.

As a example by general drying oven of the prior art, drying line (drying chamber) long 6m, walks part speed 2m/min, temperature in stove Spend 180 DEG C.And use the drying oven of the technical program, the heat energy drying fin and copper pipe is implemented separately and takes what one needs, i.e. protect Holding the temperature 140 DEG C in drying chamber, synchronize to be aided with copper pipe alignment and blow 190 DEG C of compressed airs, the device speed of service is constant, thus real Now reduction in-furnace temperature reduces body surface radiation thus reaches energy-conservation.

Seeing Fig. 1, drying oven also includes exhaustor 30 and combustor 40, and exhaustor 30 connects with drying chamber 10.Combustor 40 for promoting the temperature in drying chamber 10.

Dehydrator thermal source divides two parts to be cleaned two devices processing, and a part of steam is directly entered baking after cooling processes Inside dry chamber, dry fin and synchronize to make two device entirety gradually heat up；Another part steam is under a constant temperature or increases After auxiliary electrical heater heats up, sprayed into the inside of copper pipe by air nozzle 21 high pressure.

By bulk temperature in reduction stove, but use the compressed gas cleaning copper pipe inner wall residual oil of a small amount of high pressure-temperature, real The distribution according to need of existing heat energy, utilizes heat energy efficiency to greatest extent, thus realizes reducing dehydrator energy consumption, reach energy-conservation purpose.
